Why I want to make interstellar travel possible
The Guardian said:
Space exploration once used to be the domain of highly trained astronauts but in the near future it will be open to professionals and amateur space enthusiasts alike thanks to organisations such as Mars Society, Planetary Society and Virgin Galactic, who are giving average people like you and me (with a large bag of cash of course) the chance to have their own Yuri Gagarin moment.
One of the most unchartered areas of study in space exploration however is interstellar flight. Travelling to the moon is one thing, but designing a spaceship capable of actually reaching our nearest star system is a whole other kettle of fish.
